About 2 weeks ago a new botnet worm called "psyb0t" was discovered according to DroneBL blog post (http://www.dronebl.org/blog/8).  This worm appears to be the first botnet worm to specifically target routers and DSL modems.  It is believed the worm has been active since at least January, and it is estimated that more than 100,000 hosts have been infected so far.  The worm was first discovered by DroneBL as part of an investigation into the DDoS attacks against DroneBL's infrastructure.  A few of the malicious things the worm is designed to do include; harvest account information (usernames & passwords) through deep packet inspection, attempt to brute-force accounts, and can scan for exploitable phpMyAdmin and MySQL servers.
